This paper focuses on the effects of global factors on the saving–investment relationship. We prove that, if investments and savings are affected by idiosyncratic and global components, they must be cointegrated to obtain reliable estimates of the saving-retention coefficient. When global...

Numerous factors have been proposed in the literature as explaining the recent commodity price movements. In this paper we focus on one of the most widely discussed factors, the impact of speculative bubbles. We investigate whether commodity prices during the spike of 2007–2008 might have...

This paper analyzes the effect of changing sampling frequencies on the empirical power of "first generation" as well as "second generation" panel unit root tests.

In this paper we propose a method that allows to test for asset price bubbles. The method is mainly based on a bootstrap methodology which helps to compute the finite sample probability distribution of the asymptotic tests which were recently proposed in Phillips et al. (2011) and Phillips and...

This paper develops a dynamic intertemporal model under the hypothesis of asymmetric information for the analysis of the rate of investment in the agricultural sector. The model stresses the importance of borrowing constraints for the investment decision of firms. Using the model we derive,...

The recent reforms of the Common Agricultural Policy (CAP) of the European Union extend in a significant way the "decoupling" process started some ten years earlier. By adopting the Single Farm Payment (SFP) scheme only limited support for agriculture is tied to current production decisions....
